Designed for Total Domination

Take command immediately with Alienware's all-new, aggressive case design that includes motorised vents for managing your thermals and intimidating the competition. Available in Cosmic Black or Lunar Shadow, this sturdy desktop also offers easy access for faster upgrades.

Active Venting — This Alienware-exclusive feature helps your system stay cooler in the heat of battle. Controlled through Alienware's Command Center, the series of motorised vents can be programmed to allow greater airflow in high-performance situations.

Easy, Lighted Access - Look inside the Alienware Area-51, and you'll see why it's easier than ever to make this desktop your own. You can access most of the core components without any tools for faster upgrades. And the chassis includes two-zone, internal theater lighting — powered by rechargeable batteries — so you can service the system even when the A/C cord is unplugged.

Liquid Cooling - Eliminate distractions with high-performance CPU liquid cooling, which is more than twice as quiet as the standard heatsink and fans on other PCs. The efficient cooling also increases the reliability of your overclocked settings.
